Product Overview

 

Graphene foam presents a three-dimensional network structure similar to foam. It is composed of numerous interconnected graphene layers, which interweave and construct rich pores. The size of pores varies from nanometer to micrometer, presenting a highly open and interconnected structure as a whole. The preparation of graphene foam film by CVD method is usually carried out at high temperature (usually several hundred degrees Celsius to over one thousand degrees Celsius) and specific atmosphere (such as carbon containing gas, etc.), where the carbon source gas is decomposed and carbon atoms are grown on the substrate to form graphene under the action of a catalyst. Then, by controlling the growth conditions and subsequent treatment, graphene can form a three-dimensional foam structure. For example, using copper foil as the substrate and methane as the carbon source gas, the reaction is carried out in a high-temperature furnace. Firstly, methane decomposes at high temperatures to produce carbon atoms, which deposit on the surface of copper foil and gradually form graphene layers. Then, by controlling parameters such as reaction time and gas flow rate, graphene sheets are interconnected and grow into three-dimensional foam structures. Finally, the graphene foam is transferred from the substrate to obtain an independent graphene foam material.

The graphene foam prepared by CVD method has the advantages of high quality and regular structure. The growth process of graphene can be precisely controlled to obtain graphene foam with specific morphology and properties.

Product Features

 

Excellent electrical properties: graphene foam has good conductivity, which makes it have potential application value in the field of electronic devices. It can be used as a conductive material for the preparation of flexible electrodes, supercapacitors, etc.

Excellent mechanical performance: Although graphene foam is a lightweight material, it has high strength and toughness. Its three-dimensional structure endows it with certain compressive and tensile resistance.

Good thermal performance: graphene foam has potential applications in the field of thermal management due to its high thermal conductivity. For example, it can be used as a heat dissipation material in electronic devices, effectively conducting the heat generated inside the device and preventing damage due to overheating

Efficient adsorption performance: due to its porous structure, graphene foam has good adsorption capacity for gas, liquid and other substances in theory. It can adsorb various organic pollutants, heavy metal ions, etc..


Application Fields

 

Supercapacitor: Graphene foam, as an electrode material, can achieve high capacitive performance and fast charge discharge rate by using its high specific surface area and good conductivity, providing efficient energy storage solutions for electronic equipment.

Battery electrode material: Its three-dimensional structure can provide a good channel for ion transport in the battery, improving the charging and discharging performance and cycle life of the battery. For example, in lithium ion batteries, graphene foam can be used as a carrier of negative electrode materials to improve the conductivity and structural stability of negative electrode materials.

Hydrogen storage materials: with its porous structure and good hydrogen adsorption performance, graphene foam has the potential to be an efficient hydrogen storage material, providing a new way for the storage and utilization of hydrogen energy.

not bad
Format: Kindle
I loved the plot of this book. The characters just didn’t have a lot of depth. The connections and “love” just weren’t communicated very well in the writing. The author didn’t write the sweet psycho trope very well at all either. Lachlan was just a mess of a character.

A Beta Worth Rooting For
Format: Kindle
In Spare, Violet Fox flips the omegaverse on its head, giving us a Beta heroine determined to make her mark. Joining the Beta Trials to support her sick father, she's thrown into a pack that doesn't want her, especially the possessive Alphas. But here's the twist: their sweet Omega turns out to be her scent match. Cue the angst, forbidden tension, and a slow-burn romance that will make your heart ache in the best way. Violet Fox delivers an emotional, refreshing take on the genre, proving Betas aren't "spares." They're stars.

Beta, Alpha, Omega oh my!
Format: Kindle
Omegas are precious and given to Alphas & their packs... but the Betas want in too. To this end, the Beta government is rolling out its trial of assigning a Beta to each Alpha-Omega pack. But forcing a Beta into a pack where they are not wanted will not end well... Of course, no one expected the Omega to fall for the assigned Beta. Great read and cliffhanger

A familiar story, just with…..less.
Format: Kindle
So, as other reviewers make clear, this is very similar to Pack Darling and The Beta. It’s much closer aligned with The Beta, in plot and maybe more like Pack Darling with characters. That being said, I don’t hate this…..but it wasn’t great either. It’s both books mentioned but just….less. Less angst, less emotion, less feeling. The plot feels very half fleshed out, and the “bad guy” feels underwhelming. I didn’t really feel any real emotions from and of the male leads, except maybe Oliver. The others fell sorta flat for me. And Mika makes herself out to be this big bad ass straight outta training and then we never see it from here again with the one fitting room incident as the exception. SPOILER: The whole, “Oh, I’m actually probably an Omega, but I don’t wanna be but I do actually wanna be but no one can ever know my secret that I do nothing to hide “ thing fell so flat. She never commutes to believing she was secretly an omega, but also mentions her “secret” a lot. It just felt so manufactured. I’m intrigued enough to read part 2 and see how the author closes everything out, but this is not one I’ll recommend or ever come back to.

A good read
Format: Kindle
A good read, just fluffy cuteness, no antagonism. I like all the characters. It could have used another round of editing however, glanfds being one error that cracked me up, and my personal pet peeve was that the author kept using the word fill instead of feel, which I promise you are not interchangeable haha, but it's definitely better than the majority of books I read on here mistake-wise.
